Review on Neewer 37mm Clip-on ND 2-400 Cellphone Camera Lens Filter Kit: Adjustable Neutral Density Filter with Phone Clip for iPhone X 8 Plus 7 Plus 7 6 6S Plus Samsung HTC Motorola iPad and More Smartphones by Alan Massey

The picture on the left shows the opening of the clip that comes with Neewer 37mm ND filters. Note the one hole on the clamp. The center image shows the clamp hole that comes with the UKCOCO phone camera lens, a 37mm lens polarizer with CPL filter available from Revain. I made sure that the 37mm ND filter could be easily threaded. on the UKCOCO terminal. Pros: If you have a UKCOCO clip you can successfully use it with Neewer ND or UKCOCO CPL. If you have an LG V40 then opening the clip that comes with UKCOCO seems commonplace. - made for it. If you have another dual or triple camera smartphone, the clip supplied with UKCOCO may work better with the Neewer ND filter than the clip supplied. Cons: You may need to spend a little more money (currently $11.99) on the UKCOCO CPL and clip to use the Neewer ND filter successfully. I have to deduct one star for Neewer ND because the clip doesn't work well with my LG V40. However I also need a CPL so I still need to buy a UKCOCO filter and clip. The image to the right shows a hard drive case ideal for transporting two filters each mounted to a UKCOCO clip. Note that the filters are attached to the straps that serve to hold the hard drive in place.
